The World Bank Approach to Food Security Analysis
Summary In 1988, the Executive Directors of the World Bank agreed to a new food security initiative for Africa. The purpose of the initiative is to reduce over time Africa's pervasive hunger. To pave the way to do so, the Bank is working with other donors and African Governments to prepare Food security action plans for individual African states. The analytical elements to developing these action plans are: the macroeconomy; the microeconomy (households); food availability; food consumption; and market intermediation. Findings of the work so far include the following: 1) defining the food insecure is an effective way to map poverty; 2) food insecurity is more pervasive in Africa than anticipated; 3) increasing agricultural output in African remains an important goal; and 4) understanding the role of gender in household decsion?making is vital to improved food security
Methoden voor euthanasie op het primaire bedrijf en standaardwerkwijzen voor het doden van nertsen = Methods for on-farm euthanasia and standard operation procedures for killing of mink
A literature survey reveals several authorized methods of euthanasia. These methods were evaluated on criteria as animal welfare, effectiveness, efficiency and aesthetics of operation. Standard operation procedures for mink were drawn up
Space allowance of young goats during transportation to slaughter = Beladingsdichtheid tijdens het wegtransport van jonge geiten
Research was performed during long distance road transportations of young goats (6-8 weeks). Effects of three space allowances on physiological responses (blood parameters, heart rate and body temperature) were measured
Web-Based Learning for Emergency Airway Management in Anesthesia Residency Training
Introduction. Web-based learning (WBL) is increasingly used in medical education; however, residency training programs often lack guidance on its implementation. We describe how the use of feasibility studies can guide the use of WBL in anesthesia residency training. Methods. Two case-based WBL emergency airway management modules were developed for self-directed use by anesthesia residents. The feasibility of using this educational modality was assessed using a single cohort pretest/posttest design. Outcome measures included user recruitment and retention rate, perceptions of educational value, and knowledge improvement. The differences between pre-and postmodule test scores and survey Likert scores were analysed using the paired test. Results. Recruitment and retention rates were 90% and 65%, respectively. User-friendliness of the modules was rated highly. There was a significant improvement in perceptions of the value of WBL in the postsurvey. There was a significant knowledge improvement of 29% in the postmodule test. Conclusions. Feasibility studies can help guide appropriate use of WBL in curricula. While our study supported the potential feasibility of emergency airway management modules for training, collaboration with other anesthesia residency programs may enable more efficient development, implementation, and evaluation of this resource-intensive modality in anesthesia education and practice

Cognitive Reserve in Parkinson’s Disease: The Effects of Welsh-English Bilingualism on Executive Function
PublishedJournal ArticleObjective. Bilingualism has been shown to benefit executive function (EF) and delay the onset of Alzheimer's disease. This study aims at examining whether a bilingual advantage applies to EF in Parkinson's disease (PD). Method. In a cross-sectional outpatient cohort of monolingual English (n = 57) and bilingual Welsh/English (n = 46) speakers with PD we evaluated the effects of bilingualism compared with monolingualism on performance on EF tasks. In bilinguals we also assessed the effects of the degree of daily usage of each language and the degree of bilingualism. Results. Monolinguals showed an advantage in performance of language tests. There were no differences in performance of EF tests in monolinguals and bilinguals. Those who used Welsh less in daily life had better performance on one test of English vocabulary. The degree of bilingualism correlated with one test of nonverbal reasoning and one of working memory but with no other tests of EF. Discussion. The reasons why the expected benefit in EF in Welsh-English bilinguals with PD was not found require further study. Future studies in PD should include other language pairs, analysis of the effects of the degree of bilingualism, and longitudinal analysis of cognitive decline or dementia together with structural or functional neuroimaging.This study was funded by Economic and Social Research Council Grant RES-062-23-1931 awarded to Linda Clare (PI), John V.

Transcranial magnetic stunning of broilers: a preliminary trial to induce unconsciousness
This study was performed to identify whether non-focal transcranial magnetic stimulation (TMS) with an adapted coil for broilers has the potential for use as a non-invasive stunning method for broilers. Application of the TMS probe resulted in dominance of theta and delta waves and appearance of spikes in the electroencephalogram (EEG) after stimulation. Correlation dimension (CD) analyses of the EEG signals recorded prior to and following the application of TMS suggested that the birds might be unconscious for approximately 15 to 20 s assuming that a reduction in CD to 60% of the baseline value indicates unconsciousness. Other observations included loss of behavioural arousal or muscle tone (muscle flaccidity), and irregular heart rate after TMS. It can be suggested that TMS has the potential to be developed as a stunning method in the future. The technique, evaluated using small number of broilers in this study, requires further improvement and the use of a power supply optimised in future research. Transcranial magnetic stimulation of the brain has potential for application as a non-invasive stunning method for broilers, which could be acceptable to some religious groups opposed to the use of established or conventional stunning methods
Co-morbidity and polypharmacy in Parkinson's Disease:insights from a large Scottish primary care database
Background: Parkinson’s disease is complicated by comorbidity and polypharmacy, but the extent and patterns of
these are unclear. We describe comorbidity and polypharmacy in patients with and without Parkinson’s disease
across 31 other physical, and seven mental health conditions.
Methods: We analysed primary health-care data on 510,502 adults aged 55 and over. We generated standardised
prevalence rates by age-groups, gender, and neighbourhood deprivation, then calculated age, sex and deprivation
adjusted odds ratios (OR) and 95% confidence intervals (95% CI) for those with PD compared to those without, for
the prevalence, and number of conditions.
Results: Two thousand six hundred forty (0.5%) had Parkinson’s disease, of whom only 7.4% had no other conditions
compared with 22.9% of controls (adjusted OR [aOR] 0.43, 95% 0.38–0.49). The Parkinson’s group had more conditions,
with the biggest difference found for seven or more conditions (PD 12.1% vs. controls 3.9%; aOR 2.08 95% CI 1.84–2.35).
12 of the 31 physical conditions and five of the seven mental health conditions were significantly more prevalent in the
PD group. 44.5% with Parkinson’s disease were on five to nine repeat prescriptions compared to 24.5% of controls (aOR
1.40; 95% CI 1.28 to 1.53) and 19.2% on ten or more compared to 6.2% of controls (aOR 1.90; 95% CI 1.68 to 2.15).
Conclusions: Parkinson’s disease is associated with substantial physical and mental co-morbidity. Polypharmacy is also a
significant issue due to the complex nature of the disease and associated treatments
